In 1924,while Franco-Belgian troops occupied the Ruhr region and League of Nations members discussed the Treaty of Mutual Assistance, Boston businessman Edward Filene launched the European Peace Contest (EPC). Inspired by a similar competition held the previous year in the United States, the EPC was simultaneously launched in France, Great Britain, Germany and Italy. Popular response was impressive: in all, more than 15,000 plans were submitted, a third of them in France alone. These contests confirmed, on both sides of the Atlantic, people’s continuing interest in peace issues since the end of the Great War. The EPC revealed that there was much common ground regarding peace, as well as innovative suggestions; in that respect, it is a useful source for understanding peace values at a particular time and place. This article examines both the reflections of the French jury who assessed the plans and the contents of the winning proposals. Five years after the end of World War I, how did the contestants envision French and European peace, security and prosperity? How did they express their“will to heal” the scourge of war?
